Specification of Letters Patent. Patented July 19, 1910.

Application filed. June 17, 1909. Eerie! No. 502,670.

To all whom it may concern:

Be it known that I, FREDERICK A. WILSON, a citizen of the United States,residin at Brooklyn, county of Kings, State of ew York, have inventedcertain new and useful Improvements in Registers, of which the followingis a full, clear, and exact description.

My invention relates to im rovements in registers and ventilators,partlcularly of the type in which a perforated face plate is employedtogether with a louver or damper at erated so as to either close thepassages t rough that face plate or open them, said louver or damperperforming, when open, the function of a deflector arranged to directthe draft of air through the passages in the face plate.

The invention is of particular utility when ventilation is obtained bymeans of the blower system, since in such a use it is most important tohave effective means for controlling and holding the deflector at anydesired angle of ad ustment. It is to this feature, namely, thedeflector operating and controlling means, that my inventionparticularly relates.

In the accompanying drawings, Figure 1 illustrates on a small scale andin section my invention, the deflector being partially ex tended, saidsection being taken on the plane of the line X-X Fig. 2. Fig. 2 is afront view of a fragment of the face plate and deflector, showing theexposed end of the deflector operating device. Fig. 3 illustrates theconnection between the deflector operating device and the deflector,said view being a rear elevation and an edge elevation. Fig. 1illustrates the deflector operating device, detached.

l is a perforated face plate of any suitable design. 2 is a damper orlouver also of any suitable design. The louver is hinged within ashallow box or frame 3, arranged at the border or near the edge of theface plate 1, and at its rear. The louver 2 when closed prevents thepassage of air. When the louver 2 is moved to the position indicated inFig. 1, it not only opens the ventilator, but also stands obliquelyacross the direction of the draft, so as to cause the air to bedeflected forwardly through the openings in the face plate 1. The meansfor controlling and operating the deflector 2, in its preferred form,comprises a screw 4, having a thread of suitable pitch said screwpassing throu h a nut 5,'whic is trunnioned or suitab y mounted tooscillate or rock in an opening of substantially corresponding size 1nthe ouver 2. The front end of the screw 4 has a swivel or universalconnection with the face plate or main bod of the ventilator. In thisparticular form 0 the invention, the screw 4 has a ball-like head 6arranged in a socket 7 carried by the face plate 1. The socket 7 may beformed in any suitable manner. 8 is a slot inthe outer end of theballllke enlargement 6 suitable to receive a tool like a screw-driver,whereby said screw may be rotated. It will be noted that as the screw isrotated, the nut 5 will travel thereon, and since the latter isconnected to the deflector 2,it will impart to the latter acorresponding movement. As the deflector moves away from the face plate1, the angle of the screw 4 relatively thereto will change, but this iscompensated for by the means already described, so that danger of breaksing the threads or injuring or disturbing the parts is entirely avoided.By this means the deflector 2 is positively controlled, and allchattering or rattling is avoided. In instances where the blower systemis employed, the great necessity of having a positive means foroperating the deflector is conspicuously manifest, and it is in suchconnection that my invention has particular value.

Obviously the design of the various parts may be modified in variousways and any appropriate means may be provided at the outer side of theface plate to enable the user to manipulate the screw.

What I claim is:

1. In a register or ventilator, a plate having a draft opening therein,a movable damper at the rear thereof, an operating device thereforcomprising a screw member, and an intermediate bearlng device betweensaid screw member and said damper and relatively movable to both wherebysaid screw member may oscillate relatively thereto.

2. In a register or ventilator, a plate having a draft opening therein,a movable damper at the rear thereof, an operating device thereforcomprising a screw member, and an intermediate bearing device betweensaid screw member and said damper and relativel movable to both wherebysaid screw mem or may oscillate relatively thereto and plate, a louvertherefor at'the rear thereof, means to hinge said louver at 'the rear ofsaid plate, an operating device for said louver com rising a screw, aball-and-socket connection etween said screw and said face plate, theouter end of said ball being exposed for carried b ceive sai screw.
